SYMBIO BANK OBJECTIVES: Isolation and characterization of symbiotic soil microorganisms naturally colonizing the roots of horticultural crops or soil for horticultural practice. Identification of beneficial species and strains of microorganisms using classical, biochemical and molecular techniques. High effectiveness in vivo analyses to select the most beneficial species / strains of microorganisms for horticultural practice. Preparation of native mycorrhizal and bacterial inocula.

ACHIEVMENTS OF RHIZOSPHERE LAB Selection, identification and collecting of the most beneficial microorganism s strains for plant growth and yield, and for preparation of microbial inocula. Development of innovative bioproducts and technologies for improving soil quality and increasing growth and yield of crop plants: consortia against soil pathogens consortia for increasing availability of mineral ions consortia for stimulating root development and rhizosphere processes consortia for improvement of degraded soil Plate of BIOLOG identification system RFLP Cells of beneficial bacteria no plant roots surface Arbuscules inside of plant roots Pseudomonas sp. on selective medium Bacillus megaterium cells
Increasing the efficiency of water use by species of crop plants typical of the temperate zone (mainly fruit crops, vegetables, cereals). Improvement of soils quality by using strains of beneficial microorganisms, especially bacteria and mycorrhizal fungi. To increase the efficiency of production on small farms, technologies of microbiological fertilization of plants in conjunction with applications of organic matter and water. We offer: microbiologically enriched biopreparations for field and greenhouse applications, preparations for composting nitrogen-rich organic residues, including animal manure which contain microorganisms, humic acids and biochar. Applications of strains of microorganisms to the soil in difficult growing conditions - saline, acidic or alkaline soils will allow cultivation of plants under previously adverse conditions.
The use of our microorganisms for: improving the growth and yield of plants, preventing diseases of crop plants, microbial stimulation/stabilization of agricultural soils (e.g. mycorrhizal fungi, bacteria, humic acids, organic fertilizers, composts in no-tillage cultivation on loose soils, such as loess). Skierniewickie Microorganisms are effective in the management and reforestation of degraded and polluted soils. Reforestation of degraded arable soils as the methods of preventing desertification of existing farmland areas, especially inhorticultural crops. Preserving vulnerable arable land and bioremediation of the soil on farmlands, e.g. to reinforce the edges of terraces on which arable crops or vegetables are grown. (Deng et al. 2014)
New microbial solutions allowing agriculture to spread to the lands that have not yet been developed for agricultural purposes, necessary due to the increasing affluence of European and Chinese society and the increased demand for land for growing crops intended for animal feed (Liu et al. 2016). Research on species of fruit plants of the temperate zone that are grown in Europe and China, such as apples, apricots, pears, plums, perennial crops. Testing the effects of microorganisms on pathogens as a way of environment friendly plant protection technique. New microbial methods of food production with limited use of chemicals will improve the quality of food available in Europe and China. Antagonistic fungi inhibiting growth of B. cinerea Root system of apple tree cv. Ariwa treated with Humus Active + Aktywit PM. Fisher 2009; Ham 2009; Hartmann and Neumuller 2009)
Microbial strains we developed are helpful in bioremediation of soils contaminated with oils, synthetic pollutants or heavy metals and will allow to recover soil's health and productivity. Combined use of microbial soil improvers and organic fertilizers is the basis for sustainable production of high quality food and other agricultural goods on low quality, degraded soils. Restoration of quality/vitality of soils localized on degraded areas will help in utilization of these areas in agriculture, forestry and in social services like: tourism, sports and recreation. Production of siderophores (natural chelates) by soil bacteria Spores of mycorrhizal fungi which allow better plant growth in poor or low quality soils. Assessment of the condition and germination of beneficial fungi spores after freezing Greenhouse tests of impact of organic amendments on plant growth
